Pokemon Unite is a fun PVP battle game. You can basically battle anyone from basically any country on a team and it is fun. The main game is you can do is Purple Vs Orange which can be in 3v3 or 5v5. Often times there is limited modes also.
You can pick your favorite Pokemon to help you battle, against others and you have specials that each Pokemon can do to help you win against the opposite team.
You can add boost also to the Pokemon to help with their power up and stuff. This game is a free to play game that is on google play and ISO and Nintendo switch so it is cross-play. I honestly love this game and in my opinion it is so worth it to play. I can sometime spend hours in this game because this game is fun trying to unlock more Pokemon and level them up.
